OILING-CAN.

SPECIFICATION forming part of Letters Patent No. 358,932, dated March S, 1887,

Application iiled July 10,1886. Serial No. 207,645. (No model.)

T0 all whom, it Wray concern:

Be it known that I, THoMAs'B. JEFFERY, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinojs, have invented certain new and useful Improvements in Oiling-Gans, which are fully set forth in the following specification, reference being had to the accompanying drawings, forming a part thereof.

The purpose of my invention is to provide improved means for automatically closing the discharge-nozzles of machinery-oiling cans when the same are not in use; and it is especially designed to be applied to small Oilerssuch as are adapted to be carried in the pocket, and which for that purpose are made flat, as in the form of hollow disks with elastic sides, to which the pressure is applied to discharge the oil.

My invention consists of an interior valve closing the discharge-nozzle and having its stem suitably connected to the elastic sides of the can, so that the compression of the can, which tends to discharge the oil, opens the valve to allow the oil to escape'.

In the drawings, Figure lis an elevation of an oiling-can with one side broken away, showing the valve-actuating mechanism. Fig. 2 is atransverse vertical section through the can, showing the valve and its actuating mechan` ism in elevation. Fig. 3 is an elevation of a slightly-modiiied form of the valve-actuating mechanism.

A and A2 are the opposite elastic sides of the can.

B is the nozzle; C, a valve which closes it interiorly; C', the valve-stem; Aw, a bracket secured to the inner face ofthe side A, affording a bearing to the lower end of the valvestem C. v

Al1 is a bracket secured to the face A at about the center thereof.

D is a lever pivoted on the bracket A and connected at one end. to the valve-stem C.

A20 is a bracket secured to the inner face of the side A2 of the can and extended transversely past the arm D2 of the lever D, and having the abutment or lateral stud @20,which engages the said arm D2. It may have, also, the further stud d, engaging the arm D2 on the opposite side.

The normal position of the parts thus far described is as shown in full lines in Fig. 2, the valve C being seated in the nozzle. By the compression of the sides A and A2, or either of them, the bracket A2o is moved toward the bracket A, and the stud aengaging the arm D of the lever- D, rocks it over its pivot on the bracket A, causing the end of the arm D' to move downward and carry the valve-stem C toward the bottom of the can, sliding it in the bracket A10, and withdraw the valve C from its seat in the nozzle. \Vhen t-he pressure is removed from the sides A A2, their reaction reverses the movement of the parts, and the stud a21,engaging behind the arm D2, rocks it in the opposite direction from that iirst described, causing it to seat the valve in the nozzle.

In order to avoid the danger of imperfeetly seating the valve when the sides A and A2 become, by continued use, permanently bent inward, so that they do not react to the full distance necessary to seat the valve closely, I provide the spring E, coiled about the lower portion of the valve-stem C and stopped between the bracket A10 and a shoulder, G1, on the valve-stem. This spring tends to throw the valve-stem upward, and will seat it regardless ofthe reaction of the sides.

The form shown in Fig. 8 differs from that shown in the other figures only in appearance, not in essential action. The lever D in both forms operates substantially as a bell-crank lever, the fulerum being on the bracket A1", power being applied by the stud ai, and the resistance or weight being the valve-stem connected to the end of the arm D. In the second form, Fig. 3, the stud ai performs the functions of both the studs am and a in the first form, the slot d in the arm DIl of the lever D, in which said stud ai engages, enabling it to move the lever both ways.

I claim- 1. In combination with the nozzle and the elastic lateral walls of the can,a valve closing the nozzle interiorly, havingits stem extended between the elastic walls, a bell-crank lever pivoted upon one of the elastic walls, having one end connected to the valve-stem and the other end extended on the opposite side of the fulcrum from the nozzle and engaged by aprojection from the opposite wall, substantially as set forth.

Se saosa 2. In combination with the oiling-can having an elastic side, a valve closing the nozzle and having its stem extended substantially parallel to that side, a lever pivoted ou the interior Wall ofthe can connected to the stem, and a projection, as the bracket A20, connected to the elastic side and engaging the lever, substantially as and for the purpose set forth.

3. In combination with the oiler'having opposite elastic sides, and thevalve-steni extending` between them, a lever connected to the stem, pvoted on one of the sides and actuated by a. projection from the other, substantially as set forth.

4. In combination with the oiling-can having the elastic sides A and A2, provided, re-
